An ICO file is a small container that holds the same icon at several sizes, usually 16, 32, 48 and 256 pixels. Windows picks the right one for the taskbar, the desktop or a file list, so the icon stays sharp everywhere.
Start from a square image with a transparent background for the best result. If the source needs work first, use the Image Resizer or the Image Cropper, then convert.

ICO is the Windows icon format. One ICO file holds the same picture at several sizes, so it looks crisp in browser tabs, on the desktop and in the taskbar.
To see which sizes a file contains, open it in the ICO Analyzer.
Open the PNG to ICO converter, upload your image and pick the sizes you need. Download the ICO and use it as a favicon, shortcut or app icon.
For a favicon, 16, 32 and 48 px are enough. For Windows apps and shortcuts add 64, 128 and 256 px so the icon stays sharp on high-DPI screens.
Need an exact size? Try the Icon Resizer.
Not quite. ICO is a file format, while a favicon is the small icon a website shows in browser tabs and bookmarks. Favicons are often ICO files, but they can also be PNG or SVG.
The favicon converters make every version a site needs.
Yes. ICO to PNG extracts every size with transparency, and ICO to JPG gives you a flat image. There are also converters to WebP, SVG and Base64.
Usually the source image was too small. Start from at least 256 x 256 px, or from an SVG, which scales to any size without losing detail.
ICO is for Windows and ICNS is for macOS. For a cross-platform app you need both - use PNG to ICNS for the Mac version, or convert directly with ICO to ICNS.
